President-elect Barack Obama has no choice but to return to Keynesian economics. It is not because President Bush has mobilized the whole government and spent lots of cash to rescue difficult financial and insurance sectors, but because only the government can solve current economic problems.

If Obama must spend $1 trillion to revive the American economy, in addition to over $1 trillion already spent by the Bush Administration, then the U.S. government must pay more than $2 trillion to quiet down this financial tsunami. We are almost certain that this will take two years to complete.

$2 trillion is definitely not a small amount, and whether it will be effective or not is not yet known. But the market will one day find that the Federal Reserve is running out of ammunition, because the U.S. government can not afford to issue endless financial support. These problems cannot be solved unless many corporations and financial institutions that are no longer competitive are allowed to fail, giving the market opportunities to correct itself. The popular thought among political figures and Fed officials, however, is that no special political remedy for the credit disaster and the growing financial panic exists, and the only thing to be done is adopt a more active monetary policy.

The global economic nightmare started in September. To deal with the credit shrinking, the Fed, led by Ben Bernanke, quickly increased its assets, while commercial banks amassed frenziedly their reserve funds.

The total assets of the Fed jumped to $2.19 trillion on Nov. 19 from $1.28 trillion in early September. Reserve funds for saving institutions increased 13 times in two months, from $47 billion in early September to $653 billion on Nov. 19.

The excess growth of reserve funds, which reflects the worries of the financial institutions and the banks’ choices for avoiding or diminishing their loans, is an offsetting act to past over-loaning and speculative investment that broke the assets bubble. Credit standings of corporations and individuals are suspected at large, which makes money borrowing not as easy as before, so consumers’ loaning demands are actually decreasing and the credit market keeps freezing up.

With an approximate $4 trillion loss in house values and a $9 trillion loss in the stock market, American assets have taken a nose dive. But America is not the only nation suffering from this problem. These changes force people to alter their ways of consumption. The U.S. core Consumer Price Index dropped 0.1 percent in October, the first drop in CPI since December 1982. Deflation is thought to be out soon, while inflation is still high in many countries.

Roosevelt accepted Keynes theory to save economy by increasing governmental spending

In 2008, the financial derivatives created by investment banks in Wall Street gave rise to the biggest financial disaster since 1930. This proves the Keynesian allegation that the “market can not self correct.” Also, in this serious economic slide, “monetary-policy-is-of-no-use” rears its head and only fiscal policy can come into play.

Keynes participated in the negotiation for the Treaty of Versailles in 1919 and experienced two world wars. The great panic he had experienced cast many doubts on “the invisible hand” embraced by classical economics. Therefore, the government intervened.

Franklin Delano Roosevelt, after becoming president in 1933, accepted the Keynesian idea of saving the economy with more governmental spending. Today's governmental solutions all over the world are causing growth in the number of Keynes believers. However, in the U.S., the Fed can only control the money supply rather than how the money will flow.

When will Bernanke, and others who believe in monetary policy, find out that the monetary policy is not that effective as they have expected? The problems Obama must deal with, however, are more complicated than those in Roosevelt’s age. And even though the spending on public engineering provided jobs, Roosevelt’s New Deal was unable to end the Great Depression.

The breakdown of the investment banks in Wall Street turned big financial institutions and car makers toward the government for funding or investment. Saving corporations with government’s power, the U.S. will taste a bitter fruit like Japan in 1990s when it implemented its monetary policy. The Fed is facing a situation similar to that of Japan, in which the economy might run into a deflationary spiral with great destructive power, say, a widespread price fall.

Zero interest rate foreshadows next bubble

It is believed that the Fed will remain its policy of interest cuts if the U.S. economy is still in dark and the inflation pressure keeps weakening. The Fed, as expected, took a final decision to drop the benchmark interest to 0-0.25 percent in Tuesday. This interest cut shows the Fed has run out of its traditional policy tools.

Zero interest definitely harms depositors, but it means a loan free of charge, which might cause a high wave of speculative investments and the risk of an investment bubble. Historically, the U.S. has never dropped the interest rate to zero. The prior lowest interest rate of 0.68 percent happened on July 1, 1958.

The Fed has stated that it will invoke the help of all emergency tools, including nontraditional ones, to recover the economy if there is no room for further interest cuts. These nontraditional tools might involve a so-called quantitative easing monetary policy.

Early this month, Bernanke hinted at nontraditional steps he might take. Direct intervention in markets to lower the costs of a loan, and a large purchase of public debts and corporate debts that investors are shunning, might be the next steps to reverse the recession.

Bernanke and his colleagues promised to use “all tools available” to deal with the gravest economic stagnancy since World War Two. It is thought that Bernanke decided to do so is because he wanted to ensure that the U.S. will not relive Japan's “lost 10 years” after he leaves his post.

As Japan adopted a policy that many think is wrong, the interest rate of the yen stayed irrationally low for a long time. This policy failed to solve the deflation.

As early as 2002, Bernanke, then a Fed trustee, quoted economist Milton Friedman that if the economy gets into deflation, he will drop cash from a helicopter. Since then, the nickname “Helicopter Ben” follows him like a shadow.

The whole world has the same fashion when rescuing the economy. It does not mean that the Keynes school has won, because some theories from Friedman-led Chicago school are also adopted. The solutions by the Keynes school of economic thought are suspicious somehow. Keynes is back, but we have to look at history. After all, no economic theory can quickly and effectively rescue us from a pit of recession we have fallen into.

After the great panic in 1930, the function of bank is not just for borrowing money but moving assets and reselling them after portfolio packaging. The last few years have seen the most violent reform in financial markets, with a complexity unable to be elucidated by past economic theories.

Unquestionably, in 50 to 60 years after the war, the theories of Keynes and Friedman have changed a generation's mindsets. Now we might need a new generation of economists, a new set of thinking methods to develop a coherent and comprehensive theory to analyze and define a direction for the post-globalization economic world.


凯恩斯回来了?
● 傅来兴
  候任美国总统奥巴马毫无选择的必须重返凯恩斯(John Maynard Keynes)的怀抱。不是布什总统已发动整个政府的力量,以大量金钱来解救受困的金融及保险业,所以他必须跟下去,而是唯有政府方能解决当前的经济积弊。
  如果奥巴马必须动用到1万亿美元来振兴经济,加上布什政府已注入的1万多亿美元,美国政府必须以超过2万亿美元来消除这场金融海啸,而我们几乎锁定的时间是两年。
  这不是小数目,绝对不是,会不会有效果没人知道,但美国政府不能毫无止境地提供援助,市场有一天会发觉,美国联邦储备局弹尽粮绝。不让大批不具竞争力的企业和金融机构倒闭,让市场有机会纠正其过错,这些问题就不能获得解决。但在政治人物和央行官员的普遍想法中,眼下的信贷灾难和还在加剧的金融恐慌,没有特效的政策良药,能够做的就是更积极的通过货币政策来化解。
  今年9月份,是全球经济噩梦的开始,为了应对信贷收缩,在贝南克(Ben Bernanke)的领导下,联储局的资产以疯狂的速度膨胀,商业银行也在疯狂屯积储备资金。
  美国各联储银行的总资产由9月初的1万2800亿美元增至11月19日的2万1900亿,存款机构的储备资金在过去两个月猛增将近13倍,从9月初的470亿美元增至11月19日的6530亿美元。
  储备金过度增长折射了金融机构的担忧,也折射出银行避免或减少借贷的选择,这是对于过去过度借贷给企业和个人,进行过度投资和投机行为引发资产泡沫爆破的一种弥补行动。企业和个人的信用如今普遍受到怀疑,无法像过去那么方便借到钱,而各类消费者贷款的需求实际上减少了,信贷市场因此会继续冻结。
  美国人的资产价值暴跌,房屋价值已缩水了约4万亿美元,股市市值缩水9万亿美元,这不只是美国人的事,其他国家人民的遭遇一样。这些变化导致人民不得不改变消费习惯,美国10月份的核心消费者价格指数(CPI)较上月下跌了0.1%,是1982年12月以来首次出现的情况,通货紧缩被认为是快要出现的威胁,但通货膨胀在许多国家还是很高。
罗斯福接受凯恩斯理论
增加政府开支拯救经济
  华尔街投资银行创造的衍生金融产品,在2008年酿成1930年以来最大的金融灾难,印证了凯恩斯学派所主张“市场无法自我修正”,而且在严重的下滑形势中,“货币政策无用论”抬头,唯有财政政策(fiscal policy)才能发挥作用。
  凯恩斯参与1919年凡赛尔合约谈判,经历两次世界大战,他所身处的大恐慌使得古典学派所信仰的市场机能“一只看不见的手”受到极大的质疑,因此政府必须插手。
  1933年,罗斯福总统上台后,接受凯恩斯学派增加政府公共开支来拯救经济。如今,各国政府出台的拯救方案,让凯恩斯学派的信徒一时间多了起来。但联储局只能控制货币的供应,无法控制货币怎样流动。
  贝南克及其他同样信奉货币政策(monetary policy)的人,什么时候会发现货币政策并非其想象的那样有效。但奥巴马所碰到的难题,比罗斯福时期复杂多了,而且,尽管公共工程支出能够起到缓冲作用并提供就业,罗斯福所实施的新政,却没能结束大萧条也是事实。
  华尔街投资银行崩溃,大型金融机构、汽车制造厂及保险业要靠政府的注资或入股苦撑。以政府的力量来拯救企业,美国将体验上世纪90年代日本推行货币政策的恶果,与当时日本的境况类似,联储局也面临经济可能陷入极具破坏力的通缩性螺旋下降(deflationary spiral),即物价普遍下降的迹象。
零利率为下一波泡沫埋下伏笔
  如果美国经济仍不见起色,通胀压力继续减弱,联储局相信会延续降息的政策。周二会议上联储局果然采取了极端手段,把指标利率降至0-0.25%区间,这次降息实际上用光了联储局的传统政策工具。
  零利率肯定损害储户的利益,但零利率意味着可免费向银行贷款,可能引发投机性的投资热潮,为下一波泡沫埋下伏笔。美国历史上从未把利率降到零,历来最低利率出现在1958年7月1日调降至0.68%。
  但联储局已表态,在降息空间耗尽时动用各种紧急工具,包括利用非传统性工具来恢复经济增长。非传统性措施可能包括所谓的量化宽松货币政策。
  贝南克本月稍早已暗示可能采取的非传统步骤,或将通过直接干预市场来降低贷款成本,并通过大规模购买公债或投资者避之不及的公司债,来扭转经济衰退不断加深的局面。
  面对自二战以来最严重的经济低迷,贝南克和他的同僚承诺将动用“所有可用工具”,市场认为,贝南克是为确保在他离任后美国不会重演日本“失去的十年”而选择的做法。
  日本因推行被认为是错误的政策,使日元利率长期维持在不合理的低水平,但却无法解决通货紧缩的问题。
  早在2002年,当时还是联储局理事的贝南克引用经济学家傅利曼(Milton Friedman)的话,建议如果经济陷入通缩,就从直升机上撒钱下来。从此,“直升机贝南克”(Helicopter Ben)称号就和他如影随形。
  从全球拯救经济的一致方式来看,不能说是凯恩斯学派的胜利,以傅利曼为首的芝加哥学派的一些理论也用上了,因为凯恩斯学派所提供的解决方案也值得怀疑;凯恩斯是回来了,但我们还得回到历史去细读,毕竟没有一种经济学理论,能够迅速而有效地把我们从已陷入衰退中拯救出来。 
  自1930年经济大恐慌后,银行的功能已不只是借钱,而是移动资产,包装后再出售。过去几年是全球金融市场变革最厉害的时期,其复杂性已非过去经济学理论所能辩证。
  在战后50至60年里,凯恩斯和傅利曼的学说无疑改变了一代人的思维方式,如今我们可能需要新一代的经济学家,有一套新的思路来发展一种连贯而全面的理论,分析及为全球化后的经济世界提供思考方向。
